[Industrial applications]

 The present invention relates to a drain pipe trap, and more particularly to a drain pipe trap in which water in the pipe flows backward and swirls to effectively entangle and retain dust accompanying water, which is convenient and has a long service life.

[0002]

[Prior art]

 Generally, a drainage pipe such as a kitchen sink, a sink bowl, and a toilet bowl is provided with a trap, and as shown in FIG. 5, the drainage pipe trap is generally a drain pipe attached to the sink. The upstream end portion 11 that is connected is extended downward to form a U-shaped pipe portion 12 by curving in a U-shape at an appropriate height from the ground surface, and dust is formed on the bottom surface of the lowest portion of the U-shaped pipe portion 12. Of the U-shaped pipe portion 12 is extended to a proper height, and at the same time lower than or substantially the same as the discharge hole 121 of the U-shaped pipe portion 12 is screwed and closed by a trap cap 122 of a screw cap type. Bend to height to form the downstream end 13. Due to such a structure, the waste water such as the sink and the toilet bowl flows into the pipe from the upstream end 11 and torrently passes through the U-shaped pipe 12, and the downstream end 13 leads to the outside. In the process of further flowing out, the U-shaped pipe portion 12 at the relatively low position collects and holds the solid waste entrained in the wastewater in a group, and then opens the trap stopper 122 to discharge these wastes from the discharge hole 121. However, in view of the actual use situation, the wastewater that has flowed downward from the drain pipe to the upstream end 11 is washed away by the drop energy, causing the water seal in the U-shaped pipe portion 12 to be washed away. Can be discharged from the downstream end portion 13, and therefore, the waste originally stored in the U-shaped pipe portion 12 can also be swept away at the same time and flow to the downstream end portion 13 along with the water. The accompanying trash The purpose of staying is counterproductive, and sometimes it becomes inconvenient to remove dust by blocking the downstream end 13.

At present, there are various causes for blocking the drain pipe trap of the sink, but a relatively common thing is long garbage, and sometimes the hair that does not melt is scratched and the U-shaped tube portion 12 is scratched. There is a case where the drainage pipe embedded in the downstream end portion 13 or the wall surface or the floor surface is blocked or the drainage cannot be performed. In particular, if the buried part is severely blocked by dust, it may be necessary to smash the wall or floor to clean the inside of the drain pipe. This can lead to severe blockages, time is wasted and money is wasted.

[0004]

[Problems to be solved by the device]
